Temperature Blend Door Actuator

WARNING: This page is about a different car, the 2007 Lincoln Mark LT and 2007 Ford Pickup. However, it is still accessible from the selected car via links, so may be relevant.

An electric temperature blend door actuator is used to position the temperature blend door. The temperature blend door actuator contains a reversible electric motor to position the temperature blend door. A potentiometer is installed in the actuator to allow the EMTC module to monitor the position of the temperature blend door. The potentiometer circuit consists of a 5-volt reference signal connected to one end of a variable resistor, and a signal ground connected to the other. A signal return circuit is connected to a wiper which is driven along the variable resistor by the actuator shaft. The signal returned to the EMTC module from the wiper indicates the position of the temperature blend door.
